Technical Field
[0001] The utility model relates to the technical field of construction engineering, in particular to an automatic flap device for a discharging door of a cage of a construction elevator. Background Art
[0002] A construction elevator is a vertical transportation device used exclusively at construction sites. It is also called a construction elevator, a construction site hoist cage, or an external elevator. This type of mechanical equipment is mainly used in the construction of high-rise and super-high-rise buildings. Because of its high lifting capacity and convenient floor docking capabilities, it is one of the indispensable and important tools in modern construction. When the cage reaches the designated floor, there will inevitably be a gap between the cage discharge door and the floor platform, which poses a certain safety hazard when people enter and exit or when transporting goods.
[0003] In existing building construction, when reaching the designated floor, a flap is often built manually. After the cage discharge door is opened, the flap is built again. This design poses a great safety risk. Alternatively, the flap installed on the cage is started or closed by mechanical equipment and connecting structures. This device has a complex structure and is not related to the opening and closing of the cage discharge door, adding additional operating steps and drive structures. Utility Model Content

[0005] The technical solution adopted by the utility model to solve its technical problems is:
[0006] An automatic flap device for a cage discharge door of a construction elevator comprises a cage, a cage discharge door and a flap, wherein the cage discharge door and the flap are arranged on a side of the cage close to the landing platform, a driving mechanism is arranged on the cage, the driving mechanism is used to drive the cage discharge door to open and close up and down, the flap is used to build a transition platform between the cage and the landing platform, a support is arranged on the bottom plate of the cage, a connecting part is correspondingly arranged on the flap, the connecting part is rotatably connected to the support, and when the cage discharge door opens downward, the cage discharge door and the flap are The rotating end of the flap slides relatively until the top of the cage discharging door is lower than the rotating end of the flap. The flap is supported by the cage discharging door and rotates toward the side close to the stopping platform as the cage discharging door moves downward, until the flap is erected on the stopping platform and the bottom plate of the cage. When the cage discharging door moves upward to close, the cage discharging door and the flap slide relatively, and the flap is supported by the cage discharging door and rotates toward the side away from the stopping platform as the cage discharging door moves upward, until the cage discharging door is completely closed, and the rotating end of the flap rests on the cage discharging door.
[0007] Furthermore, a limit block is fixedly arranged on the flap or the cage for limiting the rotation angle of the flap toward the side away from the stop platform to no more than 90°, or a spring is arranged between the flap and the cage, and the spring has a restoring force to make the flap rotate toward the side close to the stop platform and be placed on the stop platform.
[0008] Furthermore, the limit block is fixedly arranged at the fixed end of the flap.
[0009] Furthermore, the limit block and the flap are fixed by welding, and the connecting part and the flap are fixed by welding.
[0010] Furthermore, the number of the connecting parts is two.
[0011] Furthermore, a sliding block or a roller is provided at the rotating end of the flap, and the sliding block or the roller moves in contact with the discharging door of the cage.
[0012] Furthermore, a sliding block or a roller is arranged on the top of the cage discharge door, and the sliding block or the roller moves in contact with the bottom of the flap.
[0013] Furthermore, reinforcing ribs are arranged on the flap.
[0014] Furthermore, the support is provided with an axial hole, and the connecting portion is a rotating shaft, and the rotating shaft is rotatably matched with the axial hole.
[0015] Furthermore, two bolt through holes are provided on the support, and two bolt avoidance holes are correspondingly provided on the bottom plate of the cage, and the support is fixed to the bottom plate of the cage by inserting bolts through the bolt through holes and the bolt avoidance holes.
[0016] The beneficial effects of the utility model are:
[0017] 1. When the cage discharge door is open, the flap rotates smoothly toward the side close to the landing platform under the support of the cage discharge door until the cage discharge door is fully opened, and the flap forms a transition platform between the cage and the landing platform to facilitate the entry and exit of personnel and materials; when the cage discharge door is closed, the flap is retracted upward under the push of the cage discharge door, and the flap rotates toward the side away from the landing platform until the cage discharge door is fully closed, and the rotating end of the flap leans against the cage discharge door. This setting links the cage discharge door with the flap, which not only solves the safety hazards of manually building the flap, but also avoids the complicated processes and structures added by adding a driving mechanism to drive the construction and storage of the flap.
[0018] 2. The flap is controlled by the limit block to control the rotation angle, ensuring that the flap stays stably and reliably within the specified position range, and finally leans against the cage discharge door, effectively preventing the flap from swinging at will and causing safety hazards. The spring set between the cage and the flap can also be used to apply compression thrust or tensile traction to the flap, so that the flap can lean against the cage discharge door and be set on the stop platform under the combined action of the spring restoring force and the gravity of the flap.
[0019] 3. The limit block is fixedly arranged at the fixed end of the flap. Arranging it at the fixed end of the flap can reduce the size of the limit block. On the one hand, it can reduce consumables, and on the other hand, it can avoid the large-volume limit block from hindering the entry and exit of personnel and materials.
[0020] 4. The limit blocks and connecting parts are fixed to the flap by welding. Compared with other connection methods, the welding connection has high strength, compact structure, good durability, and is not prone to loosening or falling off, which improves the structural stability and service life of the device.
[0021] 5. By setting the number of connections to two, the connection strength between the flap and the cage is increased, the force is dispersed, the balance is increased, and tilting and shaking due to uneven force are avoided.
[0022] 6. By adding a slider or roller to the rotating end of the flap and making it move in contact with the cage discharge door, smooth movement between the flap and the cage discharge door is achieved, reducing the friction resistance when the flap moves, making the flap open and close more smoothly, further improving the convenience of equipment operation and service life.
[0023] 7. By setting a sliding block or roller on the top of the cage discharge door, the direct friction between the cage discharge door and the bottom of the flap is reduced, making the cage discharge door smoother and easier to open and close, reducing the mechanical wear of the bottom of the flap and the cage discharge door, and extending the service life of the equipment.
[0024] 8. Reinforcement ribs are set on the flap to enhance the overall rigidity and load-bearing capacity of the flap, so that the structure can remain stable and not deformed even when subjected to heavy loads, ensuring that the flap functions normally as a transition platform while reducing the risk of damage to the equipment due to excessive force.
[0025] 9. An axial hole is set on the support and cooperates with the connecting shaft. The shaft can rotate freely in the axial hole. The most basic and traditional rotation connection method of the shaft and the axial hole is adopted. The structure is simple and easy to process and install. At the same time, the contact area between the axial hole and the shaft is large, and the axial hole has a strong constraint ability on the shaft. It has high load-bearing capacity and torsional strength, and can also maintain high-precision position control.
[0026] 10. Two bolt holes are provided on the support, and two bolt avoidance holes are provided on the bottom plate of the cage correspondingly. The support is fixed to the bottom plate of the cage by passing the bolts through the bolt holes of the support and the bolt avoidance holes on the bottom plate of the cage. The two-point fixation formed in this way can significantly improve the connection stability between the support and the bottom plate of the cage. At the same time, this detachable fixing method makes the flap device easy to install and maintain. It prevents local stress concentration and prolongs the service life of the equipment. Double-bolt connection is considered to be a reliable fixing method in engineering practice. Even if one of the bolts fails, the other bolt can temporarily maintain the connection, which buys time for troubleshooting and replacement and avoids the occurrence of sudden safety accidents.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0037] Reference Figures 1 to 5 The utility model provides an automatic flap device for a discharging door of a cage of a construction elevator.
[0038] In some embodiments, it includes a cage 1, a cage discharge door 2 and a flap 3, wherein the cage discharge door 2 and the flap 3 are arranged on one side of the cage 1 close to the landing platform 11, a driving mechanism 9 is arranged on the cage 1, and the driving mechanism 9 is used to drive the cage discharge door 2 to open and close up and down, and the flap 3 is used to build a transition platform between the cage 1 and the landing platform 11, a support 7 is arranged on the bottom plate 8 of the cage 1, and a connecting portion 6 is correspondingly arranged on the flap 3, and the connecting portion 6 is rotatably connected to the support 7. When the cage discharge door 2 opens downward, the cage discharge door 2 and the rotating ends of the flap 3 are aligned. The sliding movement continues until the top of the cage discharge door 2 is lower than the rotating end of the flap 3. The flap 3 is supported by the cage discharge door 2 and rotates toward the side close to the stop platform 11 as the cage discharge door 2 moves downward, until the flap 3 is erected on the stop platform 11 and the bottom plate 8 of the cage 1. When the cage discharge door 2 moves upward to close, the cage discharge door 2 and the flap 3 slide relative to each other. The flap 3 is supported by the cage discharge door 2 and rotates toward the side away from the stop platform 11 as the cage discharge door 2 moves upward, until the cage discharge door 2 is completely closed, and the rotating end of the flap 3 rests on the cage discharge door 2.
[0039] This solution links the opening and closing action of the cage discharge door 2 with the erection and storage action of the flap 3, thereby improving the safety of the staff when passing through the gap between the cage 1 and the landing platform 11, and also reducing the driving and installation structure. When the cage discharge door 2 is opened, the flap 3 is supported by the cage discharge door 2 and smoothly rotates toward the side close to the landing platform 11 until the cage discharge door 2 is fully opened, and the flap 3 forms a transition platform between the cage 1 and the landing platform 11, which is convenient for personnel and materials to enter and exit; when the cage discharge door 2 is closed, the flap 3 contacts the cage discharge door 2, and the flap 3 is pushed by the cage discharge door 2 to be retracted upwards until the cage discharge door 2 is fully closed, and the rotating end of the flap 3 leans on the cage discharge door 2, thus ensuring that the flap 3 can be erected for the next time under the action of gravity.
[0040] It should be noted that there is no limit to the number of supports 7, and it can be set to one. For example, the connecting part 6 is an entire long axis, the support 7 is an axial hole, and the axial hole and the long axis are rotatably connected. In order to improve the stability of the device and save costs, at least two supports 7 are set to ensure that the support 7 limits the flap 3 to prevent it from falling, and at the same time ensure that the flap 3 can rotate stably.
[0041] The support 7 is set on the bottom plate 8 of the cage 1 and at a certain distance from the side of the cage 1 close to the landing platform 11. This ensures that when the flap 3 is used to build a transition platform between the cage 1 and the landing platform 11, the flap 3 is connected to the support 7 and can be supported by two planes of the landing platform 11 and the bottom plate 8 of the cage 1. The flap 3 has multiple supporting points, which improves the stability and load-bearing capacity of the flap 3.
[0042] For the rotational connection between the support 7 and the connecting part 6, the connecting part 6 can be set as a rotating shaft or an axial hole, and the support 7 can be correspondingly set as an axial hole or a rotating shaft; or a bearing can be set between the support 7 and the connecting part 6 to maintain the relative rotation of the two; the support 7 and the connecting part 6 can also be set as shaft sections, and a shaft sleeve is set between the two, and the shaft section can rotate in the shaft sleeve; the connecting part 6 can also be set as a convex sphere, and a spherical groove that cooperates with the convex sphere for rotation is set in the support 7. The specific design form is not limited.
[0043] In some embodiments, a limit block 5 is fixedly provided on the flap 3 or the cage 1, which is used to limit the angle of rotation of the flap 3 toward the side away from the stop platform 11 to no more than 90°, or a spring is provided between the flap 3 and the cage 1, and the spring has a restoring force to make the flap 3 rotate toward the side close to the stop platform 11 and be placed on the stop platform 11.
[0044] The presence of the limit block 5 or the spring, on the one hand, can ensure that the rotating end of the flap 3 rests on the cage discharge door 2, and ensures that after the cage discharge door 2 is opened, the flap 3 can be rotated toward the side close to the stop platform 11 and set on the stop platform 11 under the combined action of gravity and the spring restoring force. On the other hand, the presence of the limit block 5 or the spring prevents the flap 3 from flipping over excessively, which would cause harm to the staff inside the cage 1.
[0045] The setting of the limit block 5 can be set on the flap 3, or on the bottom plate 8 or side wall of the cage 1, as long as the angle of rotation of the flap 3 toward the side away from the landing platform 11 can be controlled to ensure that the rotation angle of the flap 3 relative to the horizontal plane does not exceed 90 degrees. The limit block 5 can be set on the upper surface of the flap 3. In order to avoid the limit block 5 blocking the entry and exit of people, the volume can be reduced and set at the fixed end of the flap 3, or it can be set on the left and right sides of the flap 3. In this way, it can ensure that the rotation is stopped. At the same time, when the flap 3 is erected, the left and right limit blocks 5 can also serve as fences to protect the safety of people entering and exiting.
[0046] The spring can be a compression spring or a tension spring. The compression spring can be connected to the flap 3 at one end and set at the inner side of the cage 1 at the other end to apply thrust to the flap 3; or it can be set at the inner side of the cage 1 without being connected to the flap 3. When the flap 3 rotates excessively, it contacts the compression spring and is bounced to the cage discharge door 2. This makes the flap 3 have a tendency to rotate toward the side close to the landing platform 11, ensuring that the flap 3 can be set on the landing platform 11; the tension spring can be connected to the flap 3 at one end and connected to the bottom plate 8 of the cage 1 at the other end to apply traction to the flap 3, making the flap 3 have a tendency to rotate toward the side close to the landing platform 11, ensuring that the flap 3 can be set on the landing platform 11.
[0047] In some embodiments, the limit block 5 is fixedly arranged at the fixed end of the flap 3. Setting it at the fixed end of the flap 3 can reduce the size of the limit block 5, reduce consumables, and avoid the large-volume limit block 5 from hindering the entry and exit of personnel and materials.
[0048] In some embodiments, the limit block 5 is fixed to the flap 3 by welding, and the connecting portion 6 is fixed to the flap 3 by welding. Compared with other connection methods, welding connection has high strength, compact structure, good durability, and is not prone to loosening or falling off, thereby improving the structural stability and service life of the device.
[0049] In some embodiments, there are two connecting parts 6. By setting the number of connecting parts 6 to two, the connection strength between the flap 3 and the cage 1 is increased, the force is dispersed, the balance is increased, and the tilting and shaking due to uneven force are avoided. It can also ensure that when one connecting part 6 is damaged, the other can be used normally, which is convenient for replacing the damaged part.
[0050] In some embodiments, a slider 10 or a roller is provided at the rotating end of the flap 3, and the slider 10 or the roller moves in contact with the cage discharge door 2. This realizes smooth movement between the flap 3 and the cage discharge door 2, reduces the friction resistance when the flap 3 moves, makes the flap 3 open and close more smoothly, and further improves the convenience of equipment operation and service life.
[0051] In some embodiments, a sliding block or roller is provided on the top of the cage discharge door 2, and the sliding block or roller moves in contact with the bottom of the flap 3. This device is further improved to avoid direct contact between the cage discharge door 2 and the bottom of the flap 3 to generate large friction, so that the cage discharge door 2 is smoother and easier to open and close, and the mechanical wear of the bottom of the flap 3 and the cage discharge door 2 is reduced, thereby extending the service life of the equipment.
[0052] In some embodiments, the flap 3 is provided with reinforcing ribs 4. The reinforcing ribs 4 may be provided in the vertical direction, or in the transverse direction. This undoubtedly enhances the overall rigidity and bearing capacity of the flap 3, and keeps the structure stable and non-deformed even under a large load, thereby ensuring that the flap 3 functions normally as a transition platform and reducing the risk of damage to the equipment due to excessive force.
[0053] In some embodiments, the support 7 is provided with an axial hole, the connecting portion 6 is a rotating shaft, and the rotating shaft is rotatably matched with the axial hole. The support 7 is provided with an axial hole and matched with the rotating shaft of the connecting portion 6, and the rotating shaft can rotate freely in the axial hole. The most basic and traditional rotating connection method of the rotating shaft and the axial hole is adopted, which has a simple structure and is easy to process and install. At the same time, the contact area between the axial hole and the rotating shaft is large, and the axial hole has a strong constraint ability on the rotating shaft, and its bearing capacity and torsional strength are relatively high, and it can also maintain high-precision position control.
[0054] In some embodiments, two bolt through holes are provided on the support 7, and two bolt avoidance holes are correspondingly provided on the bottom plate 8 of the cage 1. The support 7 is fixed to the bottom plate 8 of the cage 1 by inserting bolts in the bolt through holes and the bolt avoidance holes. In this way, two-point fixation is formed, which can significantly improve the connection stability between the support 7 and the bottom plate 8 of the cage 1. At the same time, this detachable fixing method makes the flap 3 device easy to install and maintain. It prevents local stress concentration and prolongs the service life of the equipment. Double bolt connection is considered to be a reliable fixing method in engineering practice. Even if one of the bolts fails, the other bolt can temporarily maintain the connection, which buys time for troubleshooting and replacement and avoids the occurrence of sudden safety accidents.
